RainSmart® Drainage Cell

RainSmart® Drainage Cell is a lightweight three dimensional drainage panel with high load bearing capacity, used for subsurface water management.

ABOUT

RainSmart® drainage cell provides a perfect solution for sub-soil drainage and gas collection systems and low impact design applications such as roof gardens without traditional problems association with cracking and leakage. The drainage cell provides a uniform surface as well as an internal void space for effective drainage of excess water. 

The drainage cell system has a unique diamond cup structure which provides water retention for passive irrigation and helps building a perch water table in the above soil profile for the vegetation to flourish the prolonged dry periods. 

RainSmart® drainage cell is made from recycled polypropylene and is inert to soil borne chemicals and bacteria. RainSmart® cell’s shallow and effective drainage profile helps landscapes to make use of mature plants on roof garden which needs soil depth and water retention properties. 

High summer temperature can cause thermal expansion in  concrete and can cause waterproofing to crack. The RainSmart® drainage cell system due to its unique design and void properties helps this heat to escape, hence reducing the risk of cracking, enhancing the buildings’ life.

BENIFITS AND FEATURES 

  • High compressive load carrying capacity of up to 140 tons/m². 
  • High lateral flow capacity 
  • Maintains actual void size for effective drainage after backfill & compaction 
  • Low weight, only 3.2 kg/sqm compared to 250 kgs/sqm of gravel for the same effective drainage, hence reduces deck loads
  • Thin – reduces depth of cover and allows the use of mature planting in shallow conditions
  • Holds and creates a perch water table, providing ideal moist conditions for plant growth
  • Reduces hydrostatic forces upon sub-grade walls
  • Reduce the risk of waterproofing to crack due to thermal expansion in hot periods
  • Environmentally friendly made from selected recycled polypropylene 
  • Recharges groundwater table through principle of infiltration when used on natural ground surface
